GameBoy Advance CPU (ARM7TDMI) is very close to first ARM designs: just three stage pipeline, without cache (with higher IPC, because of better memory interface and less pipeline stalls). Because of using a 4-byte wide 24 bit memory bus, it could address up to 64MB of memory. It is an excellent platform to measure memory access behavior without the distortion of cache subsystems. You can buy dev boards with 64MB of external SDRAM, and run ucLinux (Linux for microcontrollers without MMU).
